Direct current (DC) motors are crucial in drones, robotics, and electrical devices. Conventionally, the DC motor is driven by a switching electricity converter, which utilizes electrical energy to drive mechanical motion. However, the rapid on-off switch
control the rotating speed of a DC motor to the prescribed value with a simple structure by temporarily charging counterelectromotive force of the winding of the motor in a capacitor, and supplying the counterelectromotive force charged in the capacitor suitably in the winding of the motor. CONSTIT...
The braking control system for a d.c. motor connected to a centrifugal weight has a signal emitter section (G) with a tachometer (T) and a high pass (HP) giving control signals to a frequency discriminator (FD) followed by a summing member (SU). This is followed by a low pass (TP...
It is a form of braking in which the kinetic energy of the motor is returned to the power supply system. This type of braking is possible when the driven load forces the motor to run at a speed higher than its no-load speed with a constant excitation. The motor back emf Ebis greater ...
A full-bridge driver, and especially an entirely integrated bridge driver, for driving DC motors in either direction is capable of automatically braking the motor when the motor direction is to be reversed. The bridge circuit is of H configuration and has four transistor switches connected in brid...
direction of the supply voltage is reserved, then the armature current also reserves forcing the back enf to a very high value and hence braking the motor. For series motor only armature is reversed for plugging. The diagram of separately excited and series excited motors are shown in the ...
